Capnograms

The monitor also displays an instantaneous CO
A typical capnogram is shown below:
1
Expiratory plateau (level of CO2 in lungs ceases to increase
significantly)
2 End-tidal concentration point (end of expiration phase, where etCO2 is
measured)
3 Onset of inspiration phase
4 Expiration phase
5 Baseline during inspiration
You can use capnograms to troubleshoot problems with equipment or monitor
configuration as well as to monitor a patient's clinical status. The following table
shows some of the more common problems identifiable through capnogram analysis:

Immediate and possible causes
Inadequate Seal Around Endotracheal
Tube
• Leaky or deflated endotracheal or
tracheostomy cuff
• Artificial airway that is too small for the
patient
Rebreathing
• Insufficient expiratory time
• Faulty expiratory valve
• Inadequate inspiratory flow
• Malfunction of a CO
• Partial rebreathing circuits
